Application led July 2.8, 1,909. Serial No. 510,124;` l

bracket 41, that is carried on a support 42,` fastened to the frame ofthe truck.

The

arm 38 has extending` therefromthe pins 43 .i i

thatengage the openings 35, andthe arm 39 is pinned to the piston rod 44ofthe clutch cylinder 45, byk `virtueof which the male member 26 `of theclutchdscontrolled. A guide bracket 46 with adjustablesleeves 47fastened to the truck, guides `one end of the piston rod 44, the `otherend of which is guided in the cylinder heads `48 and 49 `of thecylinder-45.` A piston 52 is fastened to the piston rod 44'an'd springs`53, 54, extend n between said piston and the cylinder heads 48 and 49.Openings 55, 56 are formed adjacent to the ends of the cylinder 45 fromwhich extends respectively thewpiping 57 and 58.` A stop `cock 5() istted in the cylinder head 48 and a stop cock 51 is fitted in thecylinder head 49. f

A hand pump 59 having the piston rod 61 with the handle 62pistonj valve63 and dis` charge valve 64 are connected with the clutch cylinder 45bymeans of the ports 65, having the stop cocks 66 and 67. The office ofthe hand pump 59 is to pump compressed air into either end of thecylinder 45, to throw the male member 26 `of the clutch into or ont ofengagement `with its accompanying female member 27, before there is anycharge of air inthe reservoir tosbedescribed. Flexible tubing 68, 69connect the piping 57. and 58 respectively to the piping 70 and 71,'whioh' latter extends lengthwise4 from one end ofthe car to the other.

said cock 72 connects the port`75 with the `port 76. Outlet ports 83 and94 are also `formed in the body of the cock 72 opposite theannular'po'rts77 and 78 respectively. A

rotative plug 99` withfthe port 114 and `handle 144 is located in thecock 72.

A bracket 80 extends from the truck 21 and carries a ournal pin 81, onwhich latter is journaled a spur gear 82, the teeth of which mesh withthe teeth of the pinion 30. A crank pin 84"extends fromthe gear 82 andsupports oneend of" the connecting rodl85, the other end of `whichylatter is :pinned toA thepiston rod 86 lcarrying the "pistonz87,`l` ofthe compressor 88..with the cyl-inderheads l 89 and 90. An inletvalve91is ,carried on V"has the spring 92 around its valve spindle 93, thetension of which tends to close the valve. Piping 95 with the checkvalve96 conducts the compressed air from the compressor 8 8 to thereservoir 97, which latter is itted with the safety valve 98.

From the reservoir 97 extends the piping *l v rif/h Check Valve andtubing 101, that in turn connects with the piping 102, extending to bothends of the car and connected with the three-way cock having the body103. The said cock has formed in its body the ports 104 and 105, thelatter connected with piping 102. An annular port 106 connects with theport 104 and an outlet 107 is formed in the body of the cock 103. A plug108 with the port 109 and handle 110 lits in the body of the said cock103. From the pipe 102 extends the piping 111 which leads to the port 75of the fourway cock having' the body 72. From the Yso port 104 of thethree-way cock having the body 103 leads the piping 112 with theflexible tubing 113 that connects with one `end of the brake cylinder115 supported on the truck 21. A piston 116 in the brake cylinder 115has connected thereto the piston rod 117 that extends through bothcylinder heads 118 and 119 thereof, and a spring 120 around vthe pistonrod 117 bears between the piston 116 and the cylinder head 118. The rod117 by means of the pin 121 is pinned to the link122, and the latter bymeans of the pin 123 is pinnedto the brake lever 124.- The latter isconnected to the brake beam 125 way.

carrying the brake shoes 126 in the ordinary The brake beam connections.maintainl the brake shoes 126 from the tires of the truck wheels,unless the piston 116-forces them in contact therewith. An accompanyingbrake beam 127 with brake shoes 128 is connected up with the truck inthe ordinary way.

To the piping 102 at eachend ofthe car is connected a signal cylinder129 'having the cylinder heads 130 and'131. A Vpiston 132 in thecylinder has formed therewith the circumferential port 133 on thesurfacev thereof and the longitudinal port 134 which connects therewith.A piston rod 135 extends from the piston 132 through the cylinder head131 and around which is located the spring 136 which bears between thehead 131 and the knurled nut 137 to maintain the piston in its normalposition. In the wall of the cylinder 129 is formed a port 138, with theends 139 and 140, that can register with the circumferential port 133.The port 138 is connected with thek piping 141 that leads 'to thewhistle 142. rlhe function of the whistle is toV apprise the operator ormotorman when the pressure in the reservoir97 is above or below apredetermined range of pressure. If the pressure rises too high thepiston 132 rises in the cylinder 129, the port 133 registers with theend 139v of the port 138, and the air flowing through the ports 134, 133and end 139 will enter the piping 141 and blow the whistle. Should thepressure fall too low the port 133 registers with the end 140 of theport 138 and the air then in asimilar manner blows the said whistle. Agage 143 is also attached to each end of the piping 102 to apprise theoperator of the pressure within the reservoir 97.

To use the invention and referring particularly yto Figs. 1 to 6, andshould there be no charge of kcompressed air inthe reservoir 97, and themembers of the clutch being unlocked, the operator closes the stopcocks' 50and 67 and opens thel stop cocks 51 and 66 to pump sufficientair ink thel cylinder 45,

by means of the hand pump 59 to Inove thek l piston 52, and with it themale member 26 of the clutch to lock it with its accompanying femalemember 27, after which the stop cocks 51 and 66 are closed. The motor,not shown, now starts the 'car and the driving axle 2,4 rotating, thecompressor 88 umps reservoir 97 by means of the piping 100, 102, y

112 and 113, to thebrake cylinder 115to setv the brakes on the truckwheels 25. The amount of pressurevbetween the brake shoes 126 and 128and said brake wheels 25is controlled by the handle 110, which regulatesthe port opening throughthe cock. When the brake shoes are to bereleased, the air pressure in the brake cylinder 115 and in the piping112 is released by turning the handle 107. Then the tension of thelspring 120 will move the piston 116 to release the brakes.l While thecompressor is being operated by virtue of the members of the clutchhaving been engaged with each other by the action of the hand pump 59,compressed air flows from the piping 102 into 110 of the cock, so thatthe port 109 registers with the annular port 106 and outlet the piping111 and through the latter to the A four-way cock with the body 72. y

The handle 144 is located atl right angles to the position shown in Fig.4`, so that compressed air flows from vthe port 75 to theL port l76`byway ofthe port 79, and from the latter through the port 114 to the port74. The air isthus forced :from the piping 111 to the piping 71 byvirtue of which the requisite pressure is maintained in theclutchcylinder 45 between the head 48 land the piston 52 thereof, to keep and27 ofthe clutch locked. When the presthe members-26 sure inthe reservoir97 has risen to its maxiy ymumy pressure, thefoperatordetaches the A ymember '2c from z they: member ,27 ofthe clutch.` "This he accomplishes'by )moving `theyhandle 144 `offthc four-way cockj72 so l `thattheV portA114 oi-the' plug 99 registers ,its head 48,by escapingthrough thepiping57;and71 and theports 1l`l4`and 94;A To conn,-r
